INVENTOR. BERNARD E. MENDELSOHN FIGIO BY AITORNEYS United States Patent3,162,282 WINDOW BRAQKET Bernard E. Mendelsohn, Waban, Mass, assignor toHarvey Window Incorporated, Dorchester, Mass. Filed Feb. 25, 1963, Ser.No. 260,741 1t Claims. (Cl. 189-76) This invention relates to stormWindows and more particularly comprises a new and improved storm windowsash. This application is a continuation in part of my copendingapplication Serial No. 84,416 dated January 23, 1961, now Patent No.3,080,622, patented March 12, 1963.

In my earlier application supra, I disclose a multi-sash tilt-type stormwindow employing special brackets at the four corners of each sash. Thebrackets disclosed in that application form housings for latches Whichnot only serve to support the Window sashes in the window frame but inaddition control the position of extendable flanges carried by thesashes that cooperate with the frame to effeet a better weather seal.

The improved brackets disclosed in the earlier application comprise thefirst embodiment of this invention and provide a self-locking type ofaction which causes the parts of the brackets to engage firmly the sidemembers of the sashes so that they do not in any way twist or tilt withrespect to the top and bottom members of the sashes. Moreover, thebrackets reduce the amount of staking required to form a permanentconnection between the brackets and the side members of the sashes.

In another embodiment of this invention the physical characteristics ofthe brackets in the earlier application are utilized in both thehorizontal top and bottom members of the sash as well as in the sidemembers. Thus, a very firm fit is provided between the brackets and allof the sash frame parts. While in the window which employs the firstembodiment of the present invention, an extendable flange forms part ofeach sash side, the window utilizing the second embodiment does notinclude the extendable flange and thus the configuration of the sashside members is appreciably different from that of the first embodiment.

My invention will be better understood and appreciated from thefollowing detailed description of two embodiments thereof, selected forpurposes of illustration and shown in the accompanying drawing, inwhich:

FIG. 1 is a fragmentary front elevation view of a sash constructed inaccordance with my invention;

FIG. 2 is an enlarged fragmentary perspective view, partly in section,showing a portion of the sash of FIG. 1;

FIG. 3 is across-sectional \dew taken along'the corresponding sectionline in FIG. 2;

FIG. 4 is a plan view of the bracket employed in the embodiment of FIG.1;

FIG. 5 is a fragmentary side view of another embodiment of the sashconstructed in accordance with this invention;

FIGS. 6, 7 and 8 are cross-sectional views taken along the correspondingsection lines in FIG. 5;

FIG. 9 is a perspective view of the lower corner bracket employed in thesash of FIG. 5; and

FIG. 10 is a perspective view. of an upper corner bracket employed inthe sash of FIG. 5.

The embodiment of the storm sash shown in FIGS. l4 includes in itsgeneral organization a sash frame 10 3,162,232 Patented Dec. 22,, 1964having a side member 12, a top member 14, a bottom member 16 and glass18. It will be appreciated that a second side member identical to theside member 12 shown in FIG. 1 extends parallel to the side member 12.on the other side of the sash.

The side member 12 is generally H-shaped in cross section as shown inFIG. 3' and includes generally parallel sides 21) and 22 interconnectedby a web or cross member 24. The H-shaped cross-sectional configurationdefines a pair of channels 26 and 28 disposed back to back and open inopposite directions. The channels are generally vertically oriented andextend from the top member 14 to the bottom member 16. A secondarychannel 3% is formed within the general confines of the channel 28 andis defined by sides 32 and 34 and panel 36. The secondary channel 39extends throughout the full length of the side member 1?. and contains alength of weather stripping as suggested at 33. The weather stripping 38is so positioned that it bears against the supporting or bearing surfaceof the storm window frame (not shown) when the sash is mounted in theframe.

The top member 14 and the bottom member 16 join the top and bottom ofthe side member 12 at mitered corners 4-9 and 42 shown in FIG. 1. Thetop member 14 and the bottom member 16 each include a channel identifiedat and 46, respectively, that form continuations of the channel 2-3 ofthe side member 12 when the three parts are assembled together. Thechannels 44 and 46 open inwardly of the sash it that is, face the insideof the dwelling upon which the storm Window is mounted.

Corner brackets 48 and 59 are employed to join the top member 1 with theside member 12 and the bottom member 16 with the side member 12,respectively. Corner bracket 5'0 is shown in cross section in FIGS. 2and 3 and in plan view in FIG. 4. The bracket includes a horizontal arm52 disposed in the channel 46 of the bottom member 16 and a vertical arm54 disposed in the channel 28 of the side member 12 The horizontal arm52 is composed of a face plate 5:: and a pair of horizontally disposedand spaced apart flanges 53 and 6th which bear against the sides of thechannel 45 in the bottom member i6. The face plate 56, the flanges 58and 6t}, and the base of the channel 46 cooperate to define an enclosedtrack within which is mounted a latch s2 described in detail below.

The vertical arm 54 of the bracket 5t includes a face plate 6 whichbears against the inner surface of the side 22 of side member 12 and aflange 66 disposed against the base of the channel 28 as defined by web24. It will be noted particularly in FIG. 3 that the flange 66 and theplate 64 fit snugly within the channel 28. It will also be noted that alip 63 is formed as an integral part of the side 22 of side member 12and is provided with an undercut inner surface '75 which engages amating beveled surface 72 formed on the end of the face plate 64 of thevertical arm 54. The undercut surface of the lip es cooperates with thegeneral character of the fit of the vertical arm 54 in the channel 28 tohold the vertical arm firmly in place. It also provides specificresistance against displacement of the vertical arm 64- in the channel28 when the vertical arm is staked in place as suggested at 74.

The horizontal and vertical arms 52 and 54 of bracket 54) areapproximately one inch in length and it is essential that in therelatively short distance provided a firm connection be made between thebracket arms and the bottom and side members of the sash. It is to benoted that the corner bracket 48 which serves the top member 14 and'theside member :12 is virtually to interconnect H-shaped in crosssectionhaving inner and outer sides 142 identical to the corner bracket 58 andspecifically is provided with a tapered surface at the end of the-faceplate to form a beveled corner which cooperates with the undercutsurface 70 provided on the lip 68 which extends the full length of theside member 12. v

A retractable flange 80 is disposed Within the channel 28 of the sidemember 12 and cooperates with a channel or track formed in the windowframe (notshown) to enhance the weather tightness of the storm window.The retractable nature of the flange 80 permits .the sash to beassembled readily as a tilt-type window within the frame, but yetprovides the full protection of the track-type windows of the prior art.Because the flange 80 may be withdrawn wholly within the confines of thechannel 28 in the side member 12, the sides may be tilted inwardlywhenthe flange is so withdrawn-to'facilitate cleaning and removal, butwhen the sash is mounted in the frame and the flange extends into thetrack orchannel of the frame, it forms a weather-tight sealalongthesides of the sash. The latch 62 slidable within the enclosedtrack defined by the horizontal arm 52 of bracket 50 and the base ofthat engages a slot 94 cut in the bottom of the panel 82 of the flange80 to support the flange in the channel 28 of the side member 12. Thetongue 92 has an enlarged'base in the form of a shoulder 96 that servesto space the tongue 92'from the plate 66 of the vertical arm 54 of thebracket 50. Thus, as is shown in FIG. 2, the tongue 92 is spaced fromthe plate 66 a distance which is adequate to receive the tine 98 formingone side of the slot 94 in the flange 80; A similar arrangement is usedto support the upper end of the flange 80.

The shoulder 96 serves, as a guide or gage .to facilitate the assemblyof the sash frame- When the bottom member 16 is secured to the sidemember12 by means of the bracket 50 and the. latch 62;.is disposed in.the position shown in FIG. 2, the shoulder 96 spacesthe tongue 92 fromthe inner surface of the plate 66 of the vertical arm of the bracket andthe "flange 80 may be slippedinto the channel 28 formed in the sidemember. By running the flange80 against the web 24 the tine 98 falls inplace behind the tongue 92. Thus, what otherwise'could be a 7 problem inassembling the window is avoided. Similarly, When the top member 14is'connected to the side member 12 the tongue (not shown) on latch 102will automati- The'latch carries anupwardly extending tongue 92 justrearwardly or inwardly of the head 90,

cally align itself withthe slot. (not shown) at the top of the flangeand slip into place.

In the embodiment er FIGS. 5-10 the sash includes and glass 118. Acorner bracket is employed to in- 55 side member 112, top member114,bottom member 116 terconnect the side member 112 and the top memberg I 114, and-a second and different bracket122 is employed to connectthe side member 112 with the bottom member 116.

The side member-112 shown in FIG. '7 is an extrusion composed ofgenerally parallel inner and outer sides 124' and 126. 'A generally Lshaped channel'128 is formed at the outer side of the member 112, whichleaves a somewhat thickened outer section in theside-wall that; isprovided withacavity 132 for supporting weather stripping 134. TheL-shaped channel 128 is partially separated from an inwardly openedchannel 136 by a pair of short ribs 138 and 140 facing; one another onthe inner .faces "of thesides 124 and 126. The ribs 138" andpltltldefine the inner extreme of the L shaped cavity 128. An

inclinedjwall-192 is provided at the outer extreme of the 7 end ofthebracket horizontalarm l66.

and 144 connected by a web 146. The web, 146 with the inner and outersides define upwardly and downwardly open channels 148 and 159. fTheouter side 144 may carry a downwardly or upwardly extending flange 152(a downwardly extending flange is shown) depending upon whether the sashis designed to be closed in a raised substantially identical to the lip68 in the side member 12 of the sash of the first embodiment.

The bottom member 116 shownin FIG. 6 is substantially identical to thebottom member 16 of the previously described embodiment. Thus, thebottom member 16 has an inwardly open channel and an upwardly extendingchannel 162, and the channel 160 receives. the horizontal 'arm of thecorner bracket 122. In FIG. 6 the horizontal member is shown to includean upwardly extending fiange 164 of the type which could cooperate withthe flange 152 shown in FIG. 8 on the top'member 114 when the two aredisposed on separate sashes.

The bracket 122 shown in FIG. 8 has substantially all of thecharacteristics of the bracket '50 shown in the previous embodiment.Thus, the bracket includes a horizontal arm 166 which fits within thechannel 160 of the bottom member 116. It will 'benoted in FIGS. 6 and 9that the horizontal tarm 166 has an inner face plate 168 and a pairof'parallel horizontal flanges 170 and 172 which bear against the upperand lower sides of the channel 160 in the bottom member. In FIG. 6 itwill be noted that a pair of ribs 174 are located at the mouth of thechannel 160, and the ribs 174 cooperate with shoulders 176 provided inthe flanges 17 0 and 1720f the horizontal arm 166 to retain the armxiynthe channel 160.- The shoulders 176 are also provided with stakingrecesses 178 along each *side of the horizontal arm, which receive thestaking protrusions 178 or dimples formed in the ribs 174 at the mouthof the channel 160 of the lower member 116. V I

The horizontal arm 166 of the bracket. 122 cooperates with the base ofthe channel 160 in the lower horizontal member 116 to define a'sleevefor the latch 180. The latch 180 may be substantially identical to thelatch 62 shown in the first embodiment but does not include the upwardlyextending tongue 92, because the sashframe does not includeanextendableflange of the type shown at 80 in the first embodiment. Accordingly, thelatch 180 only serves to support'the sash in the window frame (notshown) by means of itshead 182 which extends out the The vertical arm184 of the bracket122 is substantially L-shaped in cross section just asthe arm 54 of the bracket 50. In FIG. 7 thevertical arm 184 is shown tobe identicalin cross section'to the L-shaped channel 128 formed 7 184 isinserted in the channel 128 the two together form a substantially solidcross section. ,It will be noted that I the face plate 186 of theverticaltarm 184, which is parallel to the face plate of the"horizontal;arni,lies, flush against the inner surface of the side124fofthe sidefmember 112randthe rib'188 of the v'ertical arm 184 bearsagainst the sides of the'ribs138 and140." t he outer edgeof the faceplate 186 of arm184 is bevelled at 190 from the inner sideithereof asshown in FIG. 7, and'the bevel 190 cooperates with'the similarly shapedinclined wall 192 defining the sideof the L-shaped channelin the sidemember. The arm 184 and the side member 112 are locked together bystaking the side member at a few places as suggested at 194 in FIG. 5 inalignment with the recesses 196 provided for that purpose at the cornerof the face plate 186 and flange 188 of the vertical arm.

While the bracket 122 which joins the bottom and side members 116 and112 of the sash frame, has a horizontal arm which is generally U-shapedin cross section and a vertical arm which is L-shaped in cross section,both arms 200 and 202 of the bracket 129 are L-shaped in cross section.The vertical arm 202 is substantially identical in cross-sectional shapeto the vertical arm 184 of the corner bracket 122 as each fits into thesame L- shaped channel 128 in side member 112. Thus, the outer edge 204of the vertical arm 202 is bevelled from the inner side thereof and thecorner joining the face 2% and flange 298 is provided with a pair ofstaking recesses 21b to receive the dimples 212 formed in the inner side124 of the side member. These are suggested in FIG. 5.

The horizontal arm 200 of the bracket 120 has a face plate 214 and aflange 216 which are shown in FIG. 8 to fit within the channel 148 ofthe top member. The outer edge of the face plate 214. is bevelled fromthe in nor side as shown at 218, and the bevel mates with the undercut156 in the lip 154 of the inner side 1422 of the top member 114. Theflange 216 lies against the upper side of the web 146. The horizontal am290 is locked in place by staking the side 142 as suggested at 22.0 inFIG. 5 in alignment with the staking recesses 222 provided on the cornerof the horizontal arm 214 at the corner of the face plate 214 and flange216. By staking the top member as suggested, the horizontal aim wedgesfirmly into the bevel provided by the lip 154 and the bracket is therebysecurely locked to the upper horizontal member 114 of the sash frame.

The bracket 120 carries a swivel post 224- disposed upwardly andoutwardly of the horizontal arm 214. The swivel 224- serves as a pivotalsupport for the sash in cooperation with the swivel on the opposite sideof the sash. That is, the swivels 224 at the upper corners of each sashfit within tracks provided in the window frame and the sash pivots onthe swivels when the latches are withdrawn so that the heads 182 arefree of those same tracks. When the sash is pivoted inwardly on theswivels 22 5 it may be tilted about a substantially horizontal axisnormal to the window frame to free each of the swivels from the frame.

In each of the embodiments of the present invention the brackets areprovided with one or more arms which is generally L-shaped in crosssection and has an outwardly directed bevelled edge which mates with asimilarly shaped channel in the sash frame. Thus, the brackets 48, 50and 122 each have vertical arms which are generally L-shaped and thosearms have outwardly directed bevelled edges which bind against taperedseats in the side member of the sash frame, and those arms are locked inplace by staking which forces the bevelled edge firmly against the seat.embodiment of this invention has both horizontal and vertical arms withthe L-shaped cross-sectional configuration. Both the vertical andhorizontal arms have out- .wardly directed bevelled edges formed alongthe sides of their face plates. throughout substantially the full lengthThe bevelled The bracket 120 of the second the bracket and the parts ofthe frame which receive them. Thus, in each embodiment the bevellededges of the bracket arms prevent any relative twisting between thebracket and the frame, rocking of the frame is greatly limited, and thefirm grip is achieved with a minimum of staking.

Those skilled in the art will appreciate that numerous modifications maybe made of this invention without departing from its spirit.
